Heater problems in the winter suck. But with a little diagnosis you can usually figure out the problem. Heater cores can get clogged from time to time and this video presents a solution to that problem should you have it. BTW, the product used in the video was CLR. If you KNOW you have a clogged heater core this procedure is a good thing to try to help fix the problem. However, if you are having heating problems I would suggest you check for air in the cooling system first before performing this procedure. The #1 cause of heating problems is actually air in the cooling system. More information on how to deal with HVAC issues can be found in this article I wrote.

My cat died because it drank coolant. My older brother was working on his car, dropped a bunch of coolant on the ground. I didn't think anything of it besides of how it may stain or how messy it looked. At that point I knew nothing about cars. Later that day I find my beloved cat dead in the yard. Her eyes hazed over with a silver color. In disbelief I shook her around a bit, trying to get her to move. She didn't. Found a shovel, carried her over, dug a hole, and buried her. Don't let this happen to your animals. I got pretty emotional writing this. Her name was Grimlin. Had a very unique meow and flatish head. Extremely friendly and loyal. Which is strange for a cat it seems. Never ran from me. I called her hamburger head because of how flat her head was, and she used to nap with me on warm sunny days. I used to wake up to her licking my head which turned a small part of my hair into a cowlick. I miss my cat now.

Suggestion? Wouldn't a pressure regulator help with throttling the air and be a little safer to control? Also, pumps only put out about 10 lbs of pressure, give or take, so it would be advisable to control the amount if air to around that pressure.

Greatest way to blow out the little veins in that tiny itty bitty little heater core you know what I did Brother I literally ran a garden hose to my hot water heater cuz my garage is next to my house I Put A fitting on it and I had a valve on the hose where I could adjust the pressure I got it hot and then I screwed it to the heater hose and like you said I back flushed it backwards too and you wouldn't believe the rest that came out of there it was red literally red and it worked

Hey bro CLR is not for aluminum. Better to use a flush+cleaner solution found in many local auto parts supply chain stores. Just fyi so you don't actually cause unwanted corrosion in your heater core. Only use Aluminum safe fluids to flush and clean aluminum parts. Awesome video btw, the air hose was a new approach in my book, only issue with that is the psi overload; heater cores have something like a 10psi max intake. Avoid using too much airflow.

@waswestkan 7 лет назад

Personally I's ask the mechanic to give me an estimate as to what it would cost to replace the heater core. Given this treatment I would expect to core to spring a leak somewhat quickly. The downside is that labor needed to change a core on a care with AC would be as much an older vehicle is worth. The engineers should make the heater core an AC evaporator readily accessible. For a time in the late 80s the mid size GM cars had the blower mor evaporator and heater cor accesabl on the engine side of the firewall.

@bigshortstack2929 5 лет назад

Eric, instead or CLR, use Brake Clean. Disconnect the hoses from the core; connect a hose to the bottom core nipple that is long enough to hang down below the engine and into a catch container. Then, spray the Brake Clean into the other nipple until the core is pukeing out nothing but the brake cleaner. This may take a couple of cans of the cleaner, but is definitely "cleaner" to use and less messy. This technique is very good for cleaning out AC lines, cores, condensers, etc.

I came back to watch this video again. When I am worn out and tired, and feel that I have no need to learn I go back to an easy car subject, or to a video that I've already seen. You see, repetition is the key to learning. I love cars, so repetition doesn't bother me. EVERY time I come back and rewatch a video by this gentleman, I still manage to learn something. It isn't a waist of time like a rerun on television. :) Ericthecarguy is one of my mechanic mentors. There are few that I hold in as high as regard as him. It's impossible for any mechanic to make one video on one subject and cover everything there is to know. Eric is quite thorough, but I do enjoy my other mentors on the same subject, because every mechanic has a different way of fixing something. Even if it's mostly the same, it's still worth while. If you only know one way to fix something....what if it didn't work? Now you're stuck. All of my repairs that I've done before this video study, have dropped down to 1/3 of the time that I needed before. If it's a repair I do regularly even better. New jobs take 1/2 to 2/3 of the time that I took in the past. In fact, I took him so seriously on my first run through of this that I was oblivious to the rich humor in this video! :) So funny!

I couldn't agree more. I started helping my Dad work on his cars in the late 40's and 50's. He was a very good mechanic, then started working on my own cars when I got older. No you tube in those days. In fact no computers either. When I started turning old you tube showed up and I have found it invaluable for looking at car repairs. I talked to a mechanic at a local repair shop ( a good one ) and those guys are aware of you tube and use it also. I replaced the intake manifold on my '01 F150 a while back and I never would have attempted it until I found this great video on you tube showing in detail what I needed to know. So, hurrah for Eric and guys like him who are willing to spend the time to show us how they do things.

@tmartin67 4 года назад

Thanks for the idea of using air to reverse flush the heater core. I used water before and had no luck. I used air, then filled with water and reverse flush with air for an entire gallon. Then the CLR, and reversed flush with air again, and did another gallon of water. I did this entire process three times. Then ran water reverse through so much easier. It just flowed! I now have heat in my car that I have not had for the entire three years I have owned the Jeep. Thanks again Eric!

@leedress2187 8 лет назад

@reddwarf60 6 лет назад

Thanks for the vid Eric! Suggestion: Get an inexpensive ball valve with a 90 degree throw lever (like you probably have plumbed elsewhere in your shop air system) and screw an air hose QD fitting in one end and an appropriately-sized hose (singe barb) fitting in the other to create a "friendlier" throttle for your compressed air. Also: On later model cars a clogged cabin air filter can greatly reduce air flow over the heater core or AC evaporator, significantly diminishing the system output into the cabin. Enough that it can throw off the pressure reading on your AC manifold gauge set. Stay Dirty indeed!

@7jack7 6 лет назад

Thanks for the great vid. You might try incorporating a blow gun into the operation. It allows a lot more control of the air over a pair of vice grips. Shouldn't be too hard to adapt it to the heater hose.

@Liberty4Ever 7 лет назад

Most cooling systems run at 15 psi and the heater core won't be rated for much more than that so I would be very careful about using an air compressor unless I had a regulator set to perhaps 25 psi or less which isn't much air pressure. I would just flush it with a garden hose running very slowly. There are flush kits for that. There's also a radiator flushing chemical for $8 that I would use instead of CLR which could corrode the inside of the heater core and cause more problems later.

@allianceofsteel 10 лет назад

I've personally developed a method for using CLR to "rott" out cooling systems. I've done it on several with amazing results, I drain everything out, flush with water until you only have water in it, fill it up with a jug of clr, top it off distilled water, drive it around a couple days, drain it, flush it completely out and I do mean completely out, you don't want any clr left in the system when you are done, refill with distilled water and antifreeze. You might ask me why distilled water, well I started using it because the water here is so mineralized, I was changing out thermostats that literally had rocks growing on them from the mineral content of the water... that stuff can block wherever the coolant slows down or cools down in the system. Over kill but... how I do it and have done it for ages now. Awesome video, I've had my share of mouthfuls, facefuls, hairfuls of antifreeze.... *thumbs up*

@Krankie_V 10 лет назад

Not to mention the chlorine in most municipal water supplies has a tendency to accelerate corrosion in cooling systems. Distilled water is always a good idea

Thanks for this Eric! My son's 2000 Mitsubishi Eclipse was blowing cold air. I could hear the blend door moving, so I figured it had to be the heater core. That little trick with compressed air worked like a charm. I used duct tape instead, but I split it in half, so it was about the width of electrical tape. It also had a 170F thermostat, so I switched it back the the OEM recommended 180F. We have heat now.

Eric, you just saved me many hours of work, and potentially many hundreds of $. Thank you for this. My 21 year old Honda CR-V now has heat, where it didn't before. I built a little rig with a valve and a pressure regulator for the compressed air. Worked like a charm. Thanks again.

HAHAHAHA! Eric...you rock! Love this video! Actually...I am having the EXACT same problem as described in my 2001 Caravan SE (Shorty). This past weekend, I replaced the thermostat (thinking that was the problem) and did a flush and fill. Of course (my luck), that didn't fix it. So I determined with the help of my buddy (since I'm more of a techy guy and not a mechanic) that the problem was most likely a blockage in the heater core. I was scared to even attempt this and had succumbed to just hiring out, as my dad always did. After watching this....I think I can handle it (under the close eye and guidance of my buddy). Thanks for doing what you do!

Another excellent video. In my opinion, you have some of the best auto repair videos on RU-vid but that's why I''m surprised about a couple things in this video. First, I'm suprised that you turned the air on full blast rather than slowly cranked up the pressure. And you did that more than once. Second, I know you are big on safety but this is an instance where safety glasses were important. I confess that I rarely wear safety glasses when working on cars and truck but I would have in this case. Third, I'm not sure why you often don't show a product name. You can't be sued. It's not a copyright issue. The information would be useful to your viewers and the manufacturer of the product would be glad that you used it. My only guess is that maybe you don't want to take responsibility if it goes bad. In this case, it looked like you were using CLR. I'm wondering if a dilute mixture of vinegar would work. I use it to flush cooling systems before replacing coolant. Other than those things, I wish I had seen this video years ago when I had a plugged heater core in a minivan. The factory procedure was horrendous and involved removing the entire dashboard, etc. That would be necessary with that car if it was leaking but it was just clogged. I'll file your method in my brain for future reference. Thanks much and thanks for posting these helpful videos.

I believe the vinegar needs to be heated to work. It is a chemical reaction combined with the heat that cleans. There was no heat in this method so the vinegar wouldn't work. I am not sure about the CLR, I have two bottles, but am afraid of using it. It turns into a very thick white cream that looks like it would be difficult to flush out?

Hi Eric.. I'm just wondering.... Instead of back flushing under pressure... what would happen we were to simply reverse the hoses, so the inlet becomes the outlet etc. Would this really matter seeing as the water flows both ways? Could this be an alternative method to dislodge any gunk for a few 1,000 miles with hot coolant... then do a system flush at later date and new antifreeze etc? What's your thoughts?

I put CLR in my 2000 Ford Ranger heater core and let it sit for an hour. flushed it out a dozen times and hooked up a garden hose which ran freely. still very little Heat

@Persian5word 7 лет назад

make sure you bleed all the air out of the system. each car has bleeder point. also it might be the case that heater control valve doesn't allow full flow even tho is fully open

@sgtpeeper68 7 лет назад

Does your Ranger have a temperature gauge? Have you verified it reaches operating temp after running for a sufficient amount of time? If it doesn't, it might be your thermostat is stuck open. That will cause a reduction in heat output.

just a big warning, any time your back flushing a heater core from auto motive, please use a presser regular, weather your using air presser or a garden hose from your water tap, set the presser regulator to no more then 20 psi, city water presser can be up to or more then 60 psi, air compressor can be from 120 to 175 psi, it happened to me with a good heater core, I use a garden hose, as I turned the water on, I could hear a sound of expanding, POW, WATHER WAS EVERY WARE the like new heater core blow wide open, and had expanded so tight in the heater box I had a hard time getting it out of the heater box, never mind the big job to get at the heater core to replace it, what had happened, the core was so plugged up, it didn't let any water though, it loaded that core to the full water presser of 62 psi, these automotive cores are not made of heavy copper unlike your water to water or water to air heat exchangers in your home on your hot water heating system. so automotive ones will expand and blow open some were in the tubs or seams, I found out the hard way some 40 years ago, use a regulator, if it don't go at 30 psi drain it and add strail dary clean as we use in home heating hot water rads, let site 1 hour

@adamsroka432 7 лет назад

Or clean the system and replace the heater core, we all know it cannot all be cleaned without total replacement, unlike all the quick fix people.

@flinch622 4 года назад

Hope it went well. My comment is way late, but every once in a while hoses can delaminate internally [if they are multi layer] and block their own flow. A leak or complete failure usually is right behind such an event since mechanical structure is weak, and blisters sometimes form in the outer jacket. It's kind of rare, but since hoses are relatively cheap... I check them first. An internal flap may behave like a check valve when testing: flows ok one way, but not the other. Air works for testing, but you need to regulate pressure down to near normal operating pressures. Speaking of regulators, I hope one of Eric's friends buys him one for christmas - 120psi gives a faceful (or worse) when things are opened up. Nothing like a faceful when it's winter...

I unplugged mine simply by back flushing with a garden hose. Went from no heat to a furnace. Easy fix.

@craphittingthefan9445 7 лет назад

People please do not use compressed air use a Garden hose on low in the opposite direction of flow as you can see Eric blew it all over the place, the heater core can not take that much pressure if its clogged up your cooling system typically has only 15psi compressed air can reach over 150psi and blow the heater core all to hell, I am not sure why he chose to use this method, I expected a little more knowledge from him, so use a garden hose instead.

@mds2465 10 лет назад

Heck there are millions of people who use commercial products in their videos, does the company sue them? Probably not. And it's not like nobody knows what he's using anyways. I know he doesn't show license plates in his videos but that's understandable since that's personal property. But brand names... I just don't see how they could sue him for merely using their product that he bought in HIS video.

@eliresnick 6 лет назад

Is it fear of a lawsuit, or does the author object to the fact that whatever company made whatever product is in that heater core is not paying him for this advertisement?

@ASEWorldClassTech 7 лет назад

i use a water hose and back flush the heater core. The high flow and volume of the water hose doesn't blow up the heater core like compressed air might as it usually runs at 150psi... Then to go one step further if you park your car on some sort of hill to where the radiator cap/ Fill is the highest point of the engine then all of the coolants air pockets will come right out...

@practicalman45 4 года назад

That's gotta beat changing the heater core! I'll use my rubber tipped air blow gun (gently, because it is easy to throttle, and I don't want to "burst" my core from too much pressure...) I've also just used the garden hose for this before while in the process of flushing my whole cooling system.
